A Fiber-Optic Chronology 330 $aThis text presents the history of the development of fibre optic technology, explaining the scientific challenges that needed to be overcome, the range of applications and future potential for this fundamental communications technology. 330 $b"City of Light" tells the story of fiber optics, tracing its transformation from 19th-century parlor trick into the foundation of our global communications network. Written for a broad audience by a journalist who has covered the field for twenty years, the book is a lively account of both the people and the ideas behind this revolutionary technology. The basic concept underlying fiber optics was first explored in the 1840's when researchers used jets of water to guide light in laboratory demonstrations. The idea caught the public eye decades later when it was used to create stunning illuminated fountains at many of the great Victorian exhibitions. The modern version of fiber optics - using flexible glass fibers to transmit light - was discovered independently five times through the first half of the century, and one of its first key applications was the endoscope, which for the first time allowed physicians to look inside the body without surgery. Endoscopes became practical in 1956 when a college undergraduate discovered how to make solid glass fibers with a glass cladding. With the invention of the laser, researchers grew interested in optical communications.;While Bell Labs and others tried to send laser beams through the atmosphere or hollow light pipes, a small group at Standard Telecommunication Laboratories looked at guiding light by transparent fibers. Led by Charles K. Kao, they proposed the idea of fiber-optic communications and demonstrated that contrary to what many researchers thought glass could be made clear enough to transmit light over great distances. Following these ideas, Corning Glass Works developed the first low-loss glass fibers in 1970. From this point fiber-optic communications developed rapidly. The first experimental phone links were tested on live telephone traffic in 1977 and within half a dozen years long-distance companies were laying fiber cables for their national backbone systems. In 1988, the first transatlantic fiber-optic cable connected Europe with North America, and now fiber optics are the key element in global communications. The story continues today as fiber optics spread through the communication grid that connects homes and offices, creating huge information pipelines and replacing copper wires. The book concludes with a look at some of the exciting potential developments of this technology. 410 0$aSloan technology series. 606 $aFiber optics 608 $aElectronic books. 615 0$aFiber optics. 676 $a621.36/92 700 $aHecht$b Jeff$047627 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910450275203321 996 $aCity of light$91111945 997 $aUNINA LEADER 02567nam 2200673 a 450 001 9910789437203321 005 20200520144314.0 010 $a1-283-15265-7 010 $a9786613152657 010 $a0-12-385879-8 035 $a(CKB)2670000000092950 035 $a(EBL)727064 035 $a(OCoLC)741491886 035 $a(SSID)ssj0000507829 035 $a(PQKBManifestationID)12204192 035 $a(PQKBTitleCode)TC0000507829 035 $a(PQKBWorkID)10550148 035 $a(PQKB)11767170 035 $a(Au-PeEL)EBL727064 035 $a(CaPaEBR)ebr10480747 035 $a(CaONFJC)MIL315265 035 $a(MiAaPQ)EBC727064 035 $a(PPN)153845252 035 $a(EXLCZ)992670000000092950 100 $a20110321d2011 uy 0 101 0 $aeng 135 $aur|n|---||||| 181 $ctxt 182 $cc 183 $acr 200 10$aEngineering rock mass classification$b[electronic resource] $etunnelling, foundations, and landslides /$fBhawani Singh, R.K.
